Parts references specifically place 977542 in the alternator\/generator drive position — it is not the circulation-pump belt or the supercharger belt, which are separate parts on many of the same engines. On engines such as the KAD42P-A, three different belts serve three different accessories; ordering by engine family alone without confirming the accessory position is the most common source of wrong-belt orders on these engines. Always confirm engine model, serial number, and belt position from the Volvo Penta parts diagram before ordering.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta KAD32P \/ KAD32P-A — alternator belt position (confirm serial-number range from diagram)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAD42A \/ KAD42B \/ KAD42P-A — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAMD42A \/ KAMD42B \/ KAMD42P-A — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta TAMD42B \/ TAMD42WJ-A — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAD43P-A \/ KAD43P-B — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAMD43P \/ KAMD43P-A \/ KAMD43P-B — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAD44P \/ KAD44P-A \/ KAD44P-B \/ KAD44P-C — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAMD44P-A \/ KAMD44P-B \/ KAMD44P-C — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAD300-A — alternator belt position\u003c\/li\u003e\n\u003cli\u003eVolvo Penta KAMD300-A — alternator belt position\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eBelt arrangements can vary by engine version and serial number.

Many of these engines run two or three separate V-belts for the alternator, circulation pump, and supercharger — and they sit close together on the front of the engine, making them easy to confuse during service. 977542 is specifically the alternator drive belt. If you are replacing all belts as a set during a scheduled service, order each position separately from the Volvo Penta diagram to avoid duplication or gaps.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564069060644,"sku":"977542","price":55.1,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/e39a97c5-dec8-46ca-8a99-9cee7b6dcd90_e9efba91-444b-4264-b3e5-3a631b03cdae.png?v=1788639264","url":"https:\/\/marisolmarine.com\/products\/volvo-1385","provider":"Marisol Marine Company","version":"1.0","type":"link"}
